Passport Define: A passport is a document, issued by a national government, which certifies, for the purpose of international travel, the identity and nationality of its holder. The elements of identity are name, date of birth, sex, and place of birth. Most often, nationality and citizenship are congruent.A passport does not of itself entitle the passport holder entry into another country, nor to consular protection while abroad or any other privileges. It does, however, normally entitle the passport holder to return to the country that issued the passport. Rights to consular protection arise from international agreements, and the right to return arises from the laws of the issuing country. A passport does not represent the right or the place of residence of the passport holder in the country that issued the passport.
